A Multinode Quantum Network explained

The QuTech research group of Ronald Hanson, has built and demonstrated the first entanglement-based network connecting multiple quantum processors! This quantum network is composed of three independent nodes, called Alice, Bob and Charlie, based on diamond 💎 nitrogen-vacancy centres. The researchers achieved proof-of-principle demonstration of two key quantum network protocols: genuine multipartite entanglement distribution across all the nodes and any-to-any connectivity via entanglement swapping: Alice and Charlie are connected via quantum entanglement even without a direct physical link. This capability will be fundamental to build the future quantum internet ‼️ Paper in Science Realization of a multinode quantum network of remote solid-state qubits: M. Pompili* S. L. N. Hermans*, S.
